Abstract:

Many experiments have shown that laser diodes of poor quality often have the shortcoming of fluctuation in electric derivative curve and in optic derivative curve. The relationship between the fluctuation and the reliability of the laser diodes are discussed in this paper. Theoretical analysis and aging experiments show that if serious fluctuation occurs in electric derivative curve and in optic derivative curve, then the devices are unreliable. The electric derivative curve and optic derivative curve can be used as an indicator of the reliability of the laser diodes.

Key words: optoelectronics and laser, electric derivative, optic derivative, semiconductor laser, reliability
